Liquid Ejecting Head And Liquid Ejecting Apparatus

Abstract

A liquid ejecting head includes a nozzle configured to eject a liquid, a first flow path member that defines a portion of a flow path for supplying the liquid to the nozzle, a second flow path member that is bonded to the first flow path member to define a portion of the flow path and that is formed of a metal, and an adhesive that bonds the first flow path member and the second flow path member. The adhesive contains a water-insoluble chelate compound.

What is claimed is: 
     
         1 . A liquid ejecting head comprising:
 a nozzle configured to eject a liquid;   a first flow path member that defines a portion of a flow path for supplying the liquid to the nozzle;   a second flow path member that is bonded to the first flow path member to define a portion of the flow path and that is formed of a metal; and   an adhesive that bonds the first flow path member and the second flow path member, wherein   the adhesive contains a water-insoluble chelate compound.   
     
     
         2 . The liquid ejecting head according to  claim 1 , wherein the chelate compound is an oil-soluble benzotriazole. 
     
     
         3 . The liquid ejecting head according to  claim 2 , wherein the chelate compound is 5-carboxybenzotriazole. 
     
     
         4 . The liquid ejecting head according to  claim 1 , wherein the adhesive contains
 a multifunctional epoxy resin having two or more epoxy groups as a main agent, and   at least one of a curing accelerator or a curing agent.   
     
     
         5 . The liquid ejecting head according to  claim 1 , wherein a content of the chelate compound with respect to the adhesive is 0.56% by mass or more. 
     
     
         6 . The liquid ejecting head according to  claim 1 , wherein a content of the chelate compound with respect to the adhesive is 3.51% by mass or less. 
     
     
         7 . The liquid ejecting head according to  claim 1 , wherein a content of the chelate compound with respect to the adhesive is 0.56% by mass or more and 3.51% by mass or less. 
     
     
         8 . The liquid ejecting head according to  claim 1 , wherein the second flow path member is an electroformed filter formed of a metal including at least one of nickel or palladium. 
     
     
         9 . The liquid ejecting head according to  claim 8 , wherein
 the first flow path member is formed of a thermosetting resin, and   the liquid is supplied to the nozzle from the flow path in the first flow path member through the electroformed filter.   
     
     
         10 . The liquid ejecting head according to  claim 1 , wherein the liquid is an ultraviolet curable ink or a solvent-based ink. 
     
     
         11 . A liquid ejecting apparatus comprising:
 the liquid ejecting head according to  claim 1 ; and   a liquid storage unit that stores a liquid to be supplied to the liquid ejecting head.
